Video recorded by Fleur, LK forum
Only older sows have litters with more than 10 piglets. The litters of younger sows stop at 3-8 piglets.
The piglets suckle during their three first months, sometimes even four. They are clever at finding additional food, imitating the sow already at a very young age. The piglets in the video seems to be about a month and a half old.
